Website
ZombieCake will be one of the most fearless and fast-spreading reflection-based projects on the Binance Smart Chain. $ZC holders will receive $Cake on an hourly basis and will also have access to our unique manual lottery system whereby holders who purchase a certain number of tokens in a fixed period will be added to the next scheduled lottery draw. Nothing will stop our endeavor to conquer and dominate the network. With a pure desire to spread the contagion, our zombie horde will relentlessly infect non-$ZC holders. And, as our horde grows in size and strength, so will our dominance of the Crypto world.

ZOMBIECAKE.addLiquidity(uint256,uint256) (ZOMBIECAKE.sol#630-643) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (ZOMBIECAKE.sol#635-642)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

ZOMBIECAKE.getWinners() (ZOMBIECAKE.sol#140-157) uses a weak PRNG: "index = uint256(hash) % players.length (ZOMBIECAKE.sol#154)"

ZOMBIECAKE._transfer(address,address,uint256) (ZOMBIECAKE.sol#454-559) performs a multiplication on the result of a division:
-fees = amount.mul(totalFees).div(100) (ZOMBIECAKE.sol#521)
-lottery = fees.mul(lotteryFee).div(totalFees) (ZOMBIECAKE.sol#527)
Consider ordering multiplication before division.
